(Cross-reference of related applications)
[0001] This application is filed in US provisional applications 61 / 344,434 (filing date July 22, 2010), 61 / 470,515 (filing date April 1, 2011), and 61 / 470,520 (filing date 2011). Each of which is hereby incorporated by reference in its entirety.

[0002] Background art
[0003] Currently, the processing of biochemical samples has many important drawbacks. These necessarily entail large volumes-high reagent costs; high consumption costs; and labor intensive protocols and processes that are highly susceptible to cross contamination. For these reasons, complete control and isolation of individual samples within the biochemical process cannot currently be guaranteed.

  [0004] Applications for many biochemical processes--sequence bead formulations, pyrosequencing, nucleic acid ligation and polymerase chain reactions--but not limited to: volume size, chemical testing costs, labor costs, and reaction efficiency are obvious It is.

  [0005] Array bead formulation is a process in which small beads are coated with chemistry specific to the application. For example, in DNA replication, the beads are first coated with DNA primers prior to the amplification process. Even in modern state-of-the-art sequencers, relatively high local concentrations of target molecules are necessary for accurate sequencing. It is currently estimated that the typical protocol is that accurate sequencing is guaranteed if 80% of the processed beads are fully covered. Therefore, many beads must be used to increase statistical accuracy to ensure a relatively high concentration of the target sample. Furthermore, moving even the overcoated bead from one well to another inevitably results in a loss of both the bead and the suspending fluid. This is a result of the dead volume and inefficiency inherent in today's pipetting and fluid handling systems. This biochemical process is performed in typical volumes of 96 or 384 stationary well plates, generally ranging from 10 microliters to 200 microliters.

[0006] Another biochemical process (pyro sequencing) mixes a relatively high concentration of nucleic acid with a bead coated with a primer. Nucleic acids are formed by attaching clonal colonies on the beads. This is then amplified using emulsion-based PCR. The sequencer has many picoliter-sized wells that are large enough for a single bead and contain the appropriate enzymes needed for sequencing. Pyrosequencing uses a luciferase enzyme to generate light for readout, and the sequencer takes a picture of the added nucleotide wells. One important obstacle in this process is the ability to efficiently coat the beads with a primer. The proportion of beads using current technology is not properly coated with primer chemistry, resulting in poorer reaction efficiency. To improve bead coating efficiency using today's technology, reagent costs need to be increased beyond sustainability.

  [0007] Within the nucleic acid ligation reaction, similar biochemical processing problems arise. Nucleic acid ligation has become an important tool in modern molecular biology research to produce recombinant nucleic acid sequences. For example, nucleic acid ligase is used with restriction enzymes to insert nucleic acid fragments (often genes) into plasmids for use in genetic engineering. Nucleic acid ligation is a relatively common technique in molecular biology, where short DNA strands are ligated together by the action of an enzyme called ligase at a specific temperature (depending on the protocol used, but generally between 16 ° C and 25 ° C). Sometimes. For example, when a synthetic gene sequence is prepared in order to link two or more short DNA strand sequences, it is not possible to combine all the DNA strands and then perform a ligation reaction. This will result in a random sequence where the end of one strand leads to the start of the wrong strand. For synthetically constructed genes where the order of the genetic code is important, this incorrect sequence (ie, incorrect coordination) may not be desirable. To accomplish this technique, the combination of neighboring sequence pairs must first be ligated to yield the correct coordination. These construct pairs are then ligated to the correct coordination to build a longer synthetic construct. This process involves a large amount of complex chemical processing and manipulation. This is a completely labor intensive process or, if carried out using modern liquid processing, results in high cost of consumption and wasteful capacity loss in the well-known stationary well plate and pipette suction removal . Using modern liquid handling techniques, small volume mixing and control is also limited to the ability to aspirate and manipulate relatively small volumes. Typical volumes used in nucleic acid ligation reactions have nucleic acid chain lengths of 50 base pairs to 200 base pairs in 10-200 microliters.

[0008] Polymerase chain reaction (PCR) has been widely used to amplify target DNA and cDNA in many applications of molecular biology. PCR technology amplifies single or multiple DNAs and produces thousands to billions of copies of a particular DNA sequence. Modern PCR instruments perform the PCR process in a reaction volume of 10-200 microliters. One of the biggest obstacles to performing PCR in small volumes is the difficulty in manually manipulating small volumes of constituent reagents. The large volume size is evidence that existing technologies lack the ability to dose and mix sub-nanoliters. Furthermore, for next generation microfluidic technologies based on flow systems, these are still limited by the initial volume of dosing relative to the actual amount of sample required for the biochemical process. These microfluidic systems are also limited to control of the sample specific protocol during the biochemical process. These systems typically rely on microscale channel networks to transport and mix sub-microliter volumes. Some of the main drawbacks of these techniques are: Disposable microfluidic cards (to prevent contamination)-Lack of dynamic control of each sample (at any point in the biochemical process) Transport and mix any individual sample in), and the closed configuration of the system.

  [0009] In particular, the current method of digital polymerase chain reaction (dPCR) is accomplished by dividing the initial sample into multiple smaller volumes until one DNA template remains in each subvolume. By counting the number of positive subvolumes containing DNA, the initial copy number in the original volume can be calculated. Typically, this is a step dilution step that statistically generates a sample target of one DNA target per reaction volume. Statistically, a portion of the total volume may be tested to determine the initial copy number, thus reducing the total number of PCR reactions. However, for rare target detection, more partial volumes need to be tested to improve statistical accuracy. This results in more empty volume and larger test volume-thus using more chemical tests, time, instrumentation, sample processing and processing steps.

  [0010] In another method of dPCR, a test volume of emulsion is thereby produced in an oil-based carrier. This method can be an effort to reduce the number of equipment required and the time required to obtain results. First, the target sample is diluted and emulsified to a sufficiently small volume so that there is a statistical distribution of less than one copy per droplet in the carrier oil. The larger volume can then be treated as a single sample volume and processed using the PCR protocol. However, this method is generally limited to endpoint detection. Further measurements require the form of a flow cytometer so that the presence of a target can be detected for each flow droplet passing through the sensor. Flow cytometers are slow; expensive; specific liquid media are essential and can only detect endpoints. Endpoint detection limitations include post processing step requirements; lower sensitivity; longer time to obtain results; specificity and more measurements. Additional challenges for emulsion-based PCR methods include the required stability and control of each droplet. Additional statistical errors are brought into the process due to splash merging or flaking.

  [0011] Modern pipette and liquid handling systems cannot handle 100% of a given initial volume. For pipettes, both the liquid storage system (stationary well plate) and the mechanical movement within the system prevent complete aspiration removal of the sample. The loss or dead volume in this stationary plate can be explained by the wettability and shape of the surface, but neither of the current techniques can be explained.

  [0012] In flow systems, collecting individual biological samples during or at the end of a biochemical process has proven to be very challenging for existing technologies. A typical continuous flow system consists of pumps and reservoirs that make the easy recovery of important fluids technically difficult (especially on the microscale). In addition, within the flow system, the initial primer treatment of the system is time consuming, expensive, and, if performed incorrectly, results in a catastrophic test that requires retesting of the biological sample. Connected.

  [0013] Another disadvantage of existing biochemical processes is that nanoliter and sub-nanoliter volume biochemical processes cannot be automated. Transportation, mixing or collection of individual samples cannot be performed by existing automated techniques.

  [0014] A clearer view of the limits of the current technology in the amount of effluent remaining in a stationary well plate or in a system in a more general chemical process (such as generic microchemistry) that requires the manipulation of small volumes of fluid Can do. This is a result of the lack of the ability of current technology to dispense and control the smaller volumes required by more sophisticated molecular biology techniques, and is also a request from high efficiency.

  [0015] Accordingly, the present invention seeks to provide improved sample processing to at least overcome some of the above problems.

  [0066] Typical values for fluid density are 1,300 kg / m3 to 2,000 kg / m3 for carrier fluids, 700 kg / m3 to 990 kg / m3 for immiscible fluid cells, and 900 kg for biological samples. Within the range of values from / m3 to 1200kg / m3. Examples of one such set of hydraulic fluid and density are outlined herein, but are not limited to these; the carrier fluid is a Fluorinert FC-40 “fluoro” with a fat density of about 1,900 kg / m3. Carbonate ”; the fluid outside the synthesis liquid cell is about 920 kg / m3 of phenylmethylpolysiloxane (silicone oil) density; and the biological sample is a water-soluble base of PCR reagent with a density of about 1000 kg / m3 Solution.

The additive has a hydrophilic-lipophilic balance number in the range of 2-8. The total hydrophilic-lipophilic balance number of the combined additives is in the range of 2-8. Examples of polysorbate additives are SPAN80, SPAN65 and Tween 20, but are not limited to these. These additives in the encapsulated fluid buffer are between 0.001% and 10%.

  [0071] In some embodiments, the control surface is a hydrophobic material.

  [0072] Systems used for making and manipulating synthetic liquid cells typically include liquid handling systems under the control of a controller (such as a programmable computer). The controller is typically programmed to cause the liquid handling system to perform various steps (this program step is stored on a non-transitory computer readable medium).

[0073] Generation of a synthetic liquid cell
[0074] Referring to FIG. 1A, a biological sample 1 and a mutually immiscible flowable cell 2 placed on the free surface of a mutually immiscible carrier fluid 3 are Can be combined. In one embodiment, the control surface 4 controls the position of the immiscible flowable cell 2 using electrostatic forces. The control surface is charged and carried adjacent to the immiscible flowable cell, resulting in charge separation. For example, the control surface is given a large positive charge and the negatively charged ions in the immiscible fluid cell separate towards the charged body. The result is pole charge separation and adhesion to the charged body. Referring to FIG. 1B, a synthetic liquid cell 5 is generated.

  [0075] In another embodiment, referring to FIG. 2A, the biological sample 21 and the mutually immiscible flowable cells 22 placed on the free surfaces of the mutually immiscible carrier fluids 22 Can be combined using the control surface 23. The control surface 23 controls the position of the immiscible flowable cell 20 using a hydrophobic effect. Hydrophobic surfaces repel water-based media, but silicone-based fats can be easily moistened and controlled using hairy tension. When the control surface 23 is brought into contact with the immiscible fluid cell 20, the immiscible fluid cell 20 provides wetting to the surface of the body. The fluid cell is then transported to a location on the carrier fluid 22 by moving the control surface 23. With reference to FIG. 2B, a composite cell 24 is generated.

  [0076] In another embodiment, referring to FIG. 3A, the biological sample 31 placed on the free surface of the immiscible carrier fluid 32 and the immiscible fluid cell 30 are directional control tubes. Combined using 33. The directional control tube 33 provides an air jet that, when applied to an immiscible fluid cell 30, produces a resistance greater than the resistance of the transfer, thereby transporting the cell fluid in a controlled manner. To do. With reference to FIG. 3B, a synthetic liquid cell 34 is generated.

[0077] In another embodiment, referring to FIG. 4A, a synthetic liquid cell can be generated using the presented method and system. Referring to FIG. 4A, well plate 41 includes biological sample 42 at one or more locations (B1, B2, B3) and is covered by immiscible fluid 43. Control tube 44 holds a controllable pressure across the tube. In this mode of operation, a continuous pressure drop is retained in the tube, thereby collecting the immiscible fluid 43 in the tube as the tube moves into contact with the immiscible fluid 43. A lot of immiscible fluid 43 is collected in the tube. Referring to FIG. 4B, the control tube 44 changes shape to the biological sample 41 and collects many biological samples C1.
Referring to FIG. 4C, the control tube returns to the immiscible fluid layer and collects a lot of immiscible fluid. Following this, the control tube exits the fluid overlay and collects air before repeating the procedure at one of the same biological sample locations or a new biological sample location. Referring to FIG. 4D, the control tube is loaded with biological samples C1, C2, C3, immiscible fluid and void 45 separating the immiscible fluid and biological sample. Referring to FIG. 4E, a control tube is placed over the carrier oil layer 46 contained in the biocompatible container 47. The control tube may be in contact with the free surface of the carrier oil 46 or may be placed 0 mm to 3 mm above. The direction of flow is reversed in the control tube and the immiscible fluid, and the sample and immiscible fluid settle on the free surface of the carrier oil, creating a synthetic liquid cell. Referring to FIG. 4F, when all of the synthetic liquid cell 48 has settled, the control tube moves to a new position and precipitates the next synthetic liquid cell.

[0078] Transport of synthetic liquid cells
In another embodiment, referring to FIG. 5, the synthetic liquid cell 51 is carried on an immiscible carrier fluid 52 that uses a control surface 53. The control surface 53 controls the position of the immiscible 52 using electrostatic forces. The control surface is charged and is carried adjacent to the fluid outside the synthesis liquid cell, resulting in charge separation. For example, the control surface is given a large positive charge and the negatively charged ions in the immiscible fluid cell separate towards the charged body. The result is pole charge separation and adhesion to the charged body. This transport movement can be used to fuse one or more synthetic liquid cells or to add additional biological samples to the synthetic liquid cell.

  [0080] In another embodiment, referring to FIG. 6A, the synthetic liquid cell 61 placed on the free surface of the immiscible carrier fluid 62 can be transported using the control surface 63. The control surface 63 controls the position of the synthetic liquid cell 61 using a hydrophobic effect. Hydrophobic surfaces push back aqueous based media, but silicone-based fats can be easily moistened and controlled using hairy tension. When the control surface 63 is brought into contact with the synthetic liquid cell 61, the fluid outside the synthetic liquid cell 61 causes the surface of the main body to be wetted. The synthetic liquid cell can then be transported to a location on the carrier fluid 62 by moving the control surface 63. This transport movement can be used to fuse one or more synthetic liquid cells or to add additional biological samples to the synthetic liquid cell.

  [0081] In another embodiment, referring to FIG. 7, a synthetic liquid cell 71 placed on an immiscible carrier fluid 72 can be controlled in position using a directional control tube 73. Direction control tube 73 provides an air jet that, when applied to immiscible 71, produces a resistance greater than the resistance of the transport, thereby transporting the cell fluid in a controlled manner. This transport movement can be used to fuse one or more synthetic liquid cells or to add additional biological samples to the synthetic liquid cell.

  [0082] In another embodiment, referring to FIG. 8A, a synthetic liquid cell 81 placed in an immiscible carrier fluid 82 uses a hydrophobic protrusion 83 attached to a base 84 to temporarily Can be fixed. This transport motion can be used to fuse one or more synthetic liquid cells or add additional biological samples to the synthetic liquid cell.

  [0083] In another embodiment, the synthetic liquid cell can be moved utilizing a combination of electrostatic forces and hydrophobic effects. With reference to FIGS. 9A and 9B, the synthetic liquid cell 91 is placed in an immiscible carrier fluid 92 and placed against the hydrophobic track 93. The dynamic control surface 94 moves the synthetic liquid cell along a defined hydrophobic track using hydrostatic forces. Furthermore, the dynamic control surface 94 can be used to separate the synthetic liquid cell from the hydrophobic circular material and to move the synthetic liquid cell independently or to another hydrophobic position. This transport motion can be used to fuse one or more synthetic liquid cells or add additional biological samples to the synthetic liquid cell.

  [0084] In another embodiment, the hydrophobic disc is partially immersed in the carrier fluid.

  [0085] In another embodiment, there are multiple control surfaces so that individual synthetic liquid cells can move independently.

  [0086] In another embodiment, the transport movement is a combination of dynamic control using hydrophobic effects. The synthetic liquid cell is placed in an immiscible carrier fluid and touches the hydrophobic track. The dynamic control surface moves the synthetic liquid cell along a hydrophobic track defined using the hydrophobic effect. Furthermore, the dynamic control surface can be used to separate the synthetic liquid cell from the hydrophobic circular material and move the synthetic liquid cell independently or to another hydrophobic position. This transport motion can be used to fuse one or more synthetic liquid cells or add additional biological samples to the synthetic liquid cell.

  [0087] In another embodiment, the carrier fluid is a continuously flowing fluid and transports the synthetic liquid cell along its streamline by the resulting momentum. In another embodiment, carrier fluid momentum is assisted by a static hydrophobic surface along which the synthetic liquid cell is advanced.

[0089] Generation of a synthetic liquid cell with multiple samples
[0090] In one embodiment, with reference to FIGS. 10A-10F, a synthetic liquid cell can be generated using the presented method and system. Referring to FIG. 10A, well plate 41 includes biological sample 42 at one or more locations (B101, B102, B103) and is covered by immiscible fluid 43. Control tube 44 holds a controllable pressure across the tube. In this mode of operation, a continuous pressure drop is retained in the tube, thereby controlling the immiscible fluid 43 when the control tube 44 moves into contact with the immiscible fluid 43. Collect in tube 44. A lot of immiscible fluid 43 is collected in the tube. Referring to FIG. 10B, the control tube 44 changes shape to the biological sample 41 and collects many biological samples C101. Referring to FIG. 10C, the control tube returns to the immiscible fluid layer and collects a lot of immiscible fluid. Following this, the control tube repeats the procedure with the same biological sample or moves while still in the flowable overlay before repeating the procedure with a new biological sample location. Subsequently, following collection of the immiscible fluid and biological sample of the multi-sample synthetic liquid cell, the control tube can be removed from the immiscible oil and before repeating the new synthetic liquid cell procedure. Collect air. Referring to FIG. 10D, the control tube is loaded with biological samples C101, C102, C103 and an immiscible fluid for a multiple sample synthesis liquid cell. Referring to FIG. 10E, a control tube is placed over the carrier oil layer 46 contained in the biocompatible container 47. The control tube may be in contact with the free surface of the carrier oil 46 or may be placed 0 mm to 3 mm above. The direction of flow is reversed in the control tube and the immiscible fluid, and the sample and immiscible fluid precipitate on the free surface of the carrier oil, creating a multi-sample synthesis liquid cell. Referring to FIG. 10F, when all of the multi-sample synthesis liquid cell 48 has settled, the control tube is moved to a new position to precipitate the next multi-sample synthesis liquid cell.

  [0091] Referring to FIGS. 11A-11C, biological sample 201 and one or more positions (O1, O2) at one or more positions (S1, S2) of the free surface of mutually immiscible carrier fluid 203 O 2) mutually immiscible fluid cells 202 are combined using control surface 204. The control surface 204 controls the position of the immiscible fluid cell 202 using electrostatic forces. The control surface is charged and carried adjacent to the immiscible flowable cell 202, resulting in charge separation. For example, the control surface 204 is given a large positive charge, and the negatively charged ions in the immiscible fluid cell 202 separate toward the charged body. The result is pole charge separation and adhesion to the charged body. Referring to FIG. 11B, a synthetic liquid cell 205 is generated at one or more positions (D1, D2). The control surface 204 controls the position of the synthetic liquid cell 205 using electrostatic force. Referring to FIG. 11C, a multiple sample synthesis liquid cell 206 is created by fusing two or more synthesis liquid cells.

A second synthetic liquid cell was produced with the same reagents. However, 2% red dye in distilled water was used instead of green pigment. The colors can be distinguished by different shades of gray in the figure. The two synthetic liquid cells were fused using a hydrophobic surface (in the opposite V shape in these images) and placed in a stabilizing function on the hydrophobic disc.

The miscible fluid cells 221 can be combined using the hydrophobic effect of the tubular control surface 223. The control tube 223 controls the position of the immiscible flowable cell 221 using a hydrophobic effect. Hydrophobic surfaces push back aqueous-based media, but silicone-based fats can be easily wetted and controlled using hairy tension. Referring to FIG. 13B, when the control tube 223 is brought into contact with the immiscible flowable cell 221, the immiscible fluid cell 221 causes wetting to the body surface. The biological sample 220 is then released and contacts the immiscible fluid cell 221 on the carrier fluid 222. Referring to FIG. 13B, a synthetic liquid cell 224 is generated. Referring to FIG. 13C, a multi-sample synthesis liquid cell 225 is created by repeating this procedure with another biological sample volume.

Four individual synthetic liquid cells consist of 2% green dye, 2% blue dye, 5% yellow dye, 10 microliters of distilled water and dye-free phenylmethylpolysiloxane-based oil and 5% polysorbate additive. A 500 microliter immiscible fluid cell composed of PD5-SPAN80 (v / v) was produced. Following emulsification, the synthetic liquid cell was fused. See FIG. As is apparent from FIG. 16, the dye-free water sample is not contaminated by the colored water sample, indicating that there is no sample-to-sample transfer within the multi-sample synthesis liquid cell. Different colors can be distinguished by different shades of gray.

The direction control tube 243 supplies an air jet, and when the air jet is applied to the sample 241, it generates a resistance greater than the resistance of the transfer, thereby transporting the buffer solution 240 and the sample solution 241 in a controlled manner. . Referring to FIG. 17B, the resulting multi-sample synthesis liquid cell 244 is generated.

Referring to FIGS. 19A and 19B, a multiple sample synthesis liquid cell 290 placed on the free surface of an immiscible carrier 293 is confined between two hydrophobic circular members 291. The hydrophobic circular material 291 has a stabilizing function 292 inside thereof. As shown in FIG. 19A, these functions are used to control the sample in the synthetic liquid cell. Also, as shown in FIG. 19B, the hydrophobic circular material can be moved along the carrier fluid 293 and stably transports the multi-sample synthesis liquid cell 290.

  [0101] In another embodiment, as described with reference to FIG. 20 and with respect to FIG. 5, the multi-sample synthesis liquid cell 251 has an immiscible carrier fluid 252 with a device control surface 253 that uses electrostatic forces. Transported above.

A representative sample of 20 microliters was divided and an uncolored water sample of approximately 10 liters was pipetted into the center of the synthesis liquid cell. The resulting structure is shown in FIG.

[0107] Mechanical functions for stabilization
[0108] Referring to FIGS. 24A-24D, a synthetic liquid composed of a target sample 311 encapsulated in an immiscible buffer fluid 312 placed on the free surface of a mutually immiscible carrier fluid 313 The cell is stably placed on the hydrophobic surface 314. Hydrophobic surface 314 is placed on or within the mutually immiscible carrier fluid 313. A hydrophobic surface 314 with local stabilization function 315 controls the position of the synthetic liquid cell. Stabilization function allows generation and / or position control and / or movement control and / or mixing and / or splitting and / or splitting of biological samples placed in synthetic liquid cells and in immiscible carrier fluids Can be processed.

Encapsulated in a hydrophobic feature 404 containing approximately 1.7 microliters of target sample 301 and having an inverted V-shaped surface 304. The hydrophobic surface is placed on or within the mutually immiscible carrier fluid 303. A hydrophobic mechanism or surface 304 with local stabilization functions controls the position of the synthetic liquid cell. In one embodiment, the stabilization function is a 45 degree cut with a face depth of 2.5 mm and a thickness of 1.5 mm. This is used to control a synthetic liquid cell of microliter size. Referring to FIG. 24C, the bottom plane of the embodiment is shown. Referring to FIG. 24D, a previously described embodiment is shown with a housing 305 having an enclosure for storing carrier liquid.

  [0110] Referring to FIGS. 25A-25D, the stabilization function has a number of parameters adapted to the specified application. Two of these parameters represent functional form and functional film thickness. The functional shape affects the overall size and position control of the internal sample 321. Referring to FIG. 25A, an inverted “V” shaped stabilization function 324 controls the position of the internal sample 321 with contacts A and B as illustrated. Referring to FIG. 25B, the curvilinear stabilization function 325 has less control over the internal location of the sample. Various shapes can customize the ratio of the synthetic liquid cell of the internal sample 321 to the encapsulated buffer fluid 322. Typically, the arc shape achieves a large sample volume relative to the encapsulated fluid ratio and can maintain an uninfected sample. Referring to FIG. 25C, the stabilization function film thickness C is effective in stabilizing the synthetic liquid cell, and can be customized to the application. For larger thicknesses (typically greater than 50% of the synthetic liquid cell diameter), the stabilization properties do not improve. For control or treatment of synthetic liquid cell retention, a thickness in the range of 5% to 50% is sufficient to stabilize the synthetic liquid cell on the free carrier surface 323. The stabilizing function is placed on or in the carrier fluid. With reference to FIG. 25D, the stabilization function is a synthetic liquid cell generation and / or position control and / or movement control of a biological sample placed on an immiscible carrier fluid within the synthetic liquid cell, And / or mixing and / or splitting and / or processing is gradually weakened.

Synthetic liquid cells can be generated at discrete locations managed utilizing the stabilizing function on the hydrophobic circular material, thus improving sample tracking and / or automation and / or process control.

[0100] Transport of synthetic liquid cells with mechanical functions
[0116] In some embodiments, referring to FIG. 29, synthetic liquid cells placed on the free surfaces of mutually immiscible carrier fluids 362 can be transported using the control surface 363. The control surface 363 controls the position of the synthetic liquid cell 361 using a hydrophobic effect. Hydrophobic surfaces push back aqueous-based media, but silicone-based oils can be easily wetted and controlled using hairy tension. When the control surface 363 is in contact with the synthetic liquid cell 361, the fluid on the outside of the synthetic liquid cell 361 causes the surface of the main body to be wetted. The synthetic liquid cell can then be transported to a location on the carrier fluid 362 by moving the control surface 363. This transport motion can be used to fuse one or more synthetic liquid cells or add additional biological samples to the synthetic liquid cell.

  [0117] In another embodiment, referring to FIGS. 30A and 30B, an array of synthetic liquid cells 371 placed on the free surfaces of immiscible carrier fluids 372 is transported using control surface 373. it can. The control surface 373 controls the position of the synthetic liquid synthetic liquid cell 371 using a hydrophobic effect. Hydrophobic surfaces push back aqueous based media, but silicone-based fats can be easily wetted and controlled using hairy tension. The control surface 373 is separated by a maximum of 0.5 times the sample diameter to ensure the sample position limit. The synthetic liquid cell array 371 can then be transported to a position on the carrier fluid 372 with the control surface 373 translated. Using this transport movement with stabilization function, the synthetic liquid cell can be processed individually, ensuring the accuracy of the discrete position of the sample and / or the reference of the stabilization function position. Prevent binding and / or sample loss that is not managed by this embodiment.

[0118] Referring to FIG. 31, the synthetic liquid cell network consists of at least two stabilization sites 381 with connecting regions 382. Each stabilization site generates, and / or controls, and / or controls, and / or mixes, and / or controls the biological sample 383 that is placed in the synthetic liquid cell 384 and in the immiscible carrier fluid 385. Or it can be split and / or processed.

[0119] In some embodiments with reference to FIGS. 32A-32F, a synthetic liquid cell network is transported using a synthetic liquid cell network. Referring to FIG. 32A, the synthetic liquid cell 391 on the carrier oil 392 is installed with a set of hydrophobic circular members with a stabilizing function 393. Referring to FIG. 32B, the control tube 394 is disposed at or in a position where the synthetic liquid cell 391 is moved. Control tube 394 is placed on the free surface of carrier fluid 392 and begins to inject immiscible encapsulation buffer fluid 395. Referring to FIG. 32C, encapsulated fluid 395 moves through the network and fuses with synthetic liquid cell 391. The control tube 394 is stopped and the flow direction is reversed.
Referring to FIG. 32D, the synthetic liquid cell moves from the original stabilizing function position to the new defined position. Referring to FIG. 32E, when the synthetic liquid cell is in a new position, the flow in the control tube 394 is stopped and removed. Referring to FIG. 32F, the synthetic liquid cell is brought to a new location for processing.

  [0120] In another embodiment, two or more synthetic liquid cells are carried with the encapsulated buffer fluid in controlled ejection and collection simultaneously.

  [0121] In another embodiment, referring to FIGS. 33A-33E, a synthetic fluid network is used to transport and fuse two synthetic liquid cells. Referring to FIG. 33A, the synthetic liquid cell 401 on the carrier fluid 402 is in the hydrophobic structure 403. Referring to FIG. 33B, immiscible encapsulation buffer fluid 404 is injected over carrier fluid 402 at control location 405. Referring to FIG. 33C, immiscible encapsulation buffer fluid 404 moves through the network and fuses with synthetic liquid cell 401. Injection of immiscible encapsulation buffer fluid 404 is stopped. Referring to FIG. 33D, immiscible encapsulation buffer fluid 404 is withdrawn from control position 405 with the internal sample moving from the original position to the new position. Referring to FIG. 33E, the immiscible encapsulation buffer fluid 404 flow stops at the control position 405 when the sample is in the new position. Samples fuse to form a single sample synthesis liquid cell. The formation of complex encapsulated oil interfaces that are constrained by the control surface, carrier oil and air interface is governed by free surface energy proportional to the surface area of the encapsulated oil / air interface. When the encapsulated oil is controlled and recovered, the system minimizes the surface area and the encapsulated oil is equally removed from the network edge. This reduction of the interface from the edge of the network transports more encapsulated aqueous droplets.

The synthetic liquid cell in this photograph contains a volume of 2.5 microliters of distilled water (one sample stained red and the other stained blue). The encapsulation buffer fluid is PD5 oil-FC40 on an immiscible fluid phenylmethylpolysiloxane-immiscible fluorocarbonation carrier.

Examples of biological protocols are given in the following paragraphs.

[0131] PCR
[0132] Polymerase chain reaction (PCR) has been used extensively to amplify target DNA and cDNA in many applications of molecular biology. PCR technology amplifies single or multiple DNAs and produces thousands to billions of copies of a particular DNA sequence. Modern PCR instruments perform the PCR process within a reaction volume of 10 microliters to 200 microliters. One of the biggest obstacles to performing PCR in small volumes is the difficulty in manually manipulating small volumes of constituent reagents. Another obstacle for PCR is the difficulty of multiplexing reactions that can increase the output.

  [0133] The methods of the present invention generally relate to mixing required fluids to form a multiple sample synthesis liquid cell. In one embodiment, the target sample is an aqueous biological sample containing reagents necessary for nucleic acid amplification and the outer fluid cell is on a carrier fluid that is a fluorocarbon-based oil (FluorinertFC-40). Silicone oil (phenylmethylpolysiloxane PD 5) with polysorbate additive (SPAN80). The individual reagents are arranged so that all the required components of the PCR are arranged as individual synthetic liquid cells. This prevents cross-contamination of biological reagents. The individual synthetic liquid cell components are mixed in the correct order. The individual synthesis liquid cells are then mixed together to form a multi-sample synthesis liquid cell. The multi-sample synthesis liquid cell is then transported to a different warming zone or optical inspection zone where a quantitative measure of the product is made by fluorescence measurements. Placement of the PCR target volume within the synthesis liquid cell prevents evaporation during thermal cycling. Typical thermal cycle temperatures are in the range of 55 ° C to 95 ° C.

  [0134] In a further embodiment, the synthetic liquid cell may have individual detection marks.

  [0135] In further embodiments, a combination of post-PCR reactions may be required for further processing, including genetic sequencing. The collection and sequencing procedure for these relatively small target volumes is greatly simplified through the use of a multiple sample synthesis liquid cell. Multiple sample synthesis liquid cells following individual processing can be selectively combined to eliminate any undefined amplification or inefficient reactions from the final accumulated volume. The mixed final target volume consisting of many different target molecules is transferred to an array instrument for detailed analysis. Synthetic liquid cells facilitate 100% volume recovery of biological samples, without the need to touch any solid surface, and have the added benefit of anti-wetting properties. The fluid volume that requires thermal cycling is greatly reduced (removing all the main parts of the stationary well plate and heat resistance), and the targeted heating strategy facilitates lower power equipment and faster reaction processing times Become.

[0137] Referring to Table 1, the synthetic liquid cell successfully performed single nucleotide polymorphism detection. Two positive samples, each containing different alleles called allele 1 and allele 2, were used. Alleles were labeled with different dyes and each allele could be detected when read with the correct intensity. The template control was not added to the synthetic liquid cell and was not amplified. This was repeated in the following order: positive allele 1, no template control, positive allele 2, and finally no other template control. Referring to Table 1, the results of successful amplification performed in a synthetic liquid cell with no cross contamination between samples are shown. This shows no increase in fluorescence intensity for samples between the first and no template control following each positive sample.

  Referring to FIG. 39, an apparatus for constant temperature nucleic acid amplification of a multiplex synthetic liquid cell. Synthetic liquid cells are arranged on a circular platform, and there are three stages to synthetic liquid cell generation that move through the necessary stages of synthetic liquid cell generation, heat treatment, optical detection and removal, and into the carrier fluid There is the addition of an immiscible encapsulation buffer fluid, the addition of a lead PCR reagent to the immiscible encapsulation buffer fluid, and the addition of a sample to the synthesis liquid cell. The synthetic liquid cell is then heated to 65 ° C. for 10 minutes for biological treatment. To finish the rotation of the hydrophobic plate, the synthetic liquid cell passes through the fluorescence detection region, after which the synthetic liquid cell is removed from the carrier fluid, and then the platform returns to the initial synthetic liquid cell generation stage. The plate rotates continuously with a new synthetic liquid cell created at a speed that depends on the rotational speed of the platform.

  [0139] FIG. 40 shows an example of a disk-shaped platform (typically a hydrophobic material) that provides a network of stabilizing functions. FIG. 40A shows a board incorporated into the system. The system has a circular liquid disc with a carrier liquid retention. Rotating on the surface of this carrier oil liquid board is a PTFE board including a stabilizing function. The board can be rotated by a shaft driven by the illustrated motor transmission. The synthetic liquid cell can be dispensed to the stabilizing function from a fixed distribution pipe (not shown).

[0140] Digital PCR
[0141] Polymerase chain reaction (PCR) is a widely used molecular amplification technique. This technology has wide application in clinical diagnostics, agricultural biotechnology and bioresearch. It is routinely used for SNP detection, genetic disease diagnosis, genetic fingerprinting, forensic analysis, phenotypic expression and other types of nucleic acid analysis. The development of digital PCR expanded the use of conventional PCR. Digital PCR is a technique that amplifies a single DNA template. The appearance of the PCR method is as follows: Digital PCR by Vogelstein and Kinzler (Proc Natl Acad Sci USA 96 (16): 9236-41 (1999)), and Principleand application of digital PCR by Pohl and Shih (Expert Review Molecular Diagnostics 4 (1): 41- 47 (2004)).

  [0142] The methods of the present invention generally involve mixing and dispensing the fluids necessary to form a multiple sample synthesis liquid cell. In one embodiment, the target sample is an aqueous biological sample containing reagents necessary for nucleic acid amplification and the outer fluid cell is on a carrier fluid that is a fluorocarbon-based oil (FluorinertFC-40). Silicone oil (phenylmethylpolysiloxane PD 5) with polysorbate additive (SPAN80). The individual reagents are arranged so that all the required components of the digital PCR are arranged as individual synthetic liquid cells. This prevents cross-contamination of biological reagents. The individual synthetic liquid cell components are mixed together in the correct order. Thereafter, the individual synthesis liquid cells are sonicated to form a multi-sample synthesis liquid cell. The multi-sample synthesis liquid cell is then transported to different heating zones or optical detection zones, where product quantitative measurements are made by fluorescence measurements. The placement of the digital PCR target volume in the synthesis liquid cell prevents evaporation during thermal cycling. Typical thermal cycle temperatures are in the range of 55 ° C to 95 ° C. The multi-sample synthesis liquid cell facilitates the use of simpler inspection methods because the multi-sample synthesis liquid cell does not require 3D embedded optics for quantification measurements.

  [0143] In another embodiment, the individual synthesis liquid cells are mechanically agitated to form a multi-sample synthesis liquid cell.

[0144] Nucleic acid / DNA ligation reaction
[0145] Nucleic acid ligation reactions involve the use of nucleic acid ligases, which are enzymes used to ligate fragments of nucleic acids. In constructing long DNA strands, a number of shorter DNA fragments are ligated together and therefore a number of ligation reaction steps need to be performed to achieve these results. The product of one binding reaction becomes a fragment into another. Pairing and ligation reactions must be performed to avoid efficiency and coordination problems that affect the reaction.

  [0146] In one I embodiment, reaction reagents, ligated DNA fragments, ligase enzymes, and buffer reagents are individually pipetted into individual wells of a microtiter plate. The outer synthetic fluid, silicone oil (phenylmethylpolysiloxane (PD5)), is pipetted onto the aqueous reagent in each well to create an oil-based interface.

  [0147] Hydrophobic sampling capillary operated by automated robotic platform aspirates a lot of oil from silicone oil (phenylmethylpolysiloxane, PD5) ranging from 500 nanoliters to 2000 nanoliters from the first sampling well Followed by aspirating a target volume (aqueous reagent) of 100 nanoliters to 700 nanoliters, followed by a similar volume of silicone oil (phenylmethylpolysiloxane, PD5) ranging from 500 nanoliters to 2000 nanoliters To do. The sampling capillary then moves through the air to the next sample well. This procedure is repeated for the next sample well, i.e. the coated oil is aspirated and then the aqueous reagent is subsequently aspirated. The hydrophobic sampling capillary then translates until a set number of samples are aspirated. Hydrophobic sampling capillaries hold a series of individual separate (suctioned during translation) liquids separated by air at this point.

[0148] Hydrophobic sampling capillaries translate on the processing platform. The direction of flow in the hydrophobic sampling capillaries is reversed, and each fluid row, which is an individual synthetic liquid cell, is dispensed onto the surface of a carrier oil (fluorocarbon-based oil (Fluorinert FC-40)). The hydrophobic sampling capillary translates between the individual liquid preparations to the initial position of the new synthetic liquid cell. The synthetic liquid cell is dispensed to connect with a hydrophobic disc that secures the synthetic liquid cell position. An array of synthetic liquid cells that combine to give the final DNA synthesis construction is placed on a single hydrophobic circle. The dispensing process produces a series of synthetic liquid cells that are placed on a hydrophobic disc and separated by a distance in the range of 0.5 mm to 10 mm.

  [0149] In the case of a single sample synthetic liquid cell, the control surface operated by an automated robotic platform creates a synthetic liquid cell combination pair, and the reagents in the synthetic liquid cell act as a hair-like tension. Combine and mix with. Or, if a fluid cell network is used, then a synthetic fluid network injection / recovery immiscible encapsulation buffer fluid control is performed to combine the synthetic liquid cell pairs and the reagents in the synthetic liquid cell bind. Mix.

  [0150] These reagents include neighboring DNA fragments and other reagents necessary for the ligation reaction to occur. A synthetic liquid cell is controlled at a specific temperature condition at a specific time to cause a ligation reaction. A typical condition for guaranteeing the ligation reaction of fragments whose adhesion is stopped is 16 ° C. for 1 hour. After this ligation reaction step, a further pair combination of neighboring synthetic liquid cells is made at the appropriate temperature and processed to produce longer fragments. This process is repeated until the desired final fragment length is reached. The newly created synthetic DNA strand is then aspirated and stored for future use.

[0151] The production of a synthetic liquid cell greatly simplifies the method of DNA ligation. The smaller reaction volume that is not normally used in this process ensures higher reaction efficiency and faster reaction time. The combination of target DNA strand fragments in each subsequent paired ligation reaction is greatly simplified and the overall number of liquid manipulations is greatly reduced because the entire sequence of the target DNA synthesis liquid cell is hydrophobic. This is because they are arranged at the same location on the sex circle network. Coalescence by this method is easily realized by manipulating the position of the synthetic liquid cell. This method of ligation is particularly useful when the product of one ligation step is required for another step.

  [0152] The use of synthetic liquid cells greatly simplifies the procedure of collecting these relatively small target volumes. Synthetic liquid cells following individual treatments can be selectively combined to eliminate any inactive samples or inefficient reactions of the ligation reaction process. The synthetic liquid cell facilitates 100% volume recovery of biological samples because there is no need to touch any solid surface and there is the added benefit of anti-wetting properties.

  [0153] More particularly, a multiple sample synthesis liquid cell may be used. The multi-sample synthesis liquid cell is controlled at a specific temperature condition, and a ligation reaction occurs at a specific time. A typical condition for guaranteeing the ligation reaction of fragments whose adhesion is stopped is 16 ° C. for 1 hour. Following the ligation reaction, nucleic acid amplification is performed to selectively and accurately amplify the target and the region of the next ligation step. After this step, the internal sample is combined for each sequence pair, additional reagents are added if necessary, and processed at the appropriate temperature to produce longer fragments. This process is repeated until the desired final fragment length is reached. The newly created synthetic DNA strand is then aspirated and stored for future use.

  [0154] The generation of multiple sample synthesis liquid cells greatly simplifies the DNA ligation reaction scheme. A smaller reaction volume not normally used in this process ensures higher reaction efficiency and faster reaction time. The combination of target DNA strand fragments for each subsequent paired ligation reaction is greatly simplified and the total number of liquid manipulations is greatly reduced because the entire sequence of the target DNA sample is one multiple sample synthesis. This is because they are arranged at the same place on the liquid cell. The coalescence of the internal sample by this method is easily realized by manipulating the outer oil surface position within the position function of the hydrophobic surface. This method of ligation is particularly useful when the product of one ligation step is required for another step.

[0155] Genetic sequence bead coat
[0156] Genetic sequence bead formulations are processes in which small beads are coated with chemical elements that are specific to the application. In one embodiment, the bead coating prior to genetic disease screening is achieved by creating a synthetic liquid cell with an aqueous solution of beads as the target volume. The specific primer chemical element used to cover the bead is introduced into the fluid cell by a capillary tube and when the aqueous droplets are precipitated directly into the fluid cell, the target volume binds and the primer chemical element mixes with the aqueous bead solution. And united.

  [0157] In another embodiment, the target volume coalesces and mixes upon operation of generating a synthetic liquid cell of primer elements and then combining with a synthetic liquid cell containing an aqueous bead solution.

  [0158] These methods provide a convenient way to manipulate and combine sub-microliter fluid volumes that are currently impossible to achieve using conventional techniques, thus reducing the initial sample volume by reducing the reaction volume. Reduce and improve bead coating efficiency. Further processing using PCR and thermal cycling and genetic sequencing is specific to the application.

  [0159] The use of a synthetic liquid cell greatly simplifies the procedure of collecting these relatively small target volumes. Synthetic liquid cells following individual processing can be selectively combined to eliminate any inactive beads. Synthetic liquid cells facilitate 100% volume recovery of biological samples as there is no need to touch any solid surface and there is the added benefit of anti-wetting properties. These features facilitate the automation of biochemical processes.

  [0160] The present invention is not limited to the described embodiments and may vary depending on configuration and details. For example, the encapsulation buffer fluid may be any suitable liquid or gas, most commonly a liquid. The carrier fluid may be any suitable liquid or gas, most commonly a liquid. Encapsulation and carrier fluids may be selected such that the functional groups of the fluid limit the diffusion of carrier fluid molecules into the encapsulating fluid and vice versa. This immiscibility constraint can also be applied between the encapsulating fluid and the target sample, and molecular diffusion is limited by the different functional groups of the constituent fluid. For example, the phenylmethyl functionality present in phenylmethylpolysiloxane (silicone oil) for encapsulating fluids is immiscible with the perfluoro functionality present in fluorocarbon-based carrier oils commonly selected for carrier fluids. These two fats are also immiscible with aqueous based samples common in molecular biochemistry. In addition, fluids of different densities are selected so that the carrier fluid has the highest density, forms the lowest layer of fluid, the encapsulated fluid has the lowest density, and the target sample is the carrier fluid and the encapsulated fluid. It is also convenient to have an intermediate density.
